SPECIFICATION forming part of Letters Patent No. 780,272, dated January1'7, 1905.

Application filed March 30, 1901. Serial No. 53,669.

To all whom, mfr/,y @Qn/cern:

Be it known that I, Donn E. FELT, a citizen of the United States,residing in Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Tabulating-Machines, of whichthe following is a specification.

This invention relates to `tabulating machines.

In the use of these machines it is sometimes desirable to tabulateamounts upon a less number of lines, counting vertically, than the sheetis adapted to hold; and my object in the invention has been to providethe machine with means whereby the operator may be informed when he hastabulated any predetermined number of amounts. In other words, I havedevised and applied to a tabulatingmachine suitable mechanism adapted tobe set in advance of the tabulating and which when any predeterminednumber of lines, either the entire number which the sheet will hold orany less number, have been tabulated the machine will automaticallylock, so that no further amounts can be printed until the lock isreleased.

The invention is an improvement upon the machine shown in myapplication, Serial No. 36,951, filed November 19, 1900, and sincepatented in Patent N o. 694,955, dated March 1I, 1902, in which I showmeans for locking the machine when the bottom of the paper is reached,the locking mechanism being controlled by the paper itself; but in thepresent invention I do not rely upon the paper for this purpose, thoughthe machine may embody both the mechanism of my said application andthat of the present invention also.

The nature of the present improvements will be fully understood from thespecification given below and is also fully illustrated in theaccompanying drawings, in which- Figures 1 and 2 are longitudinalvertical sections of a tabulating-machine embodying my invention, thefirst showing the parts in normal position; and the latter being' partlybroken away and showing the parts in their locked position. Fig. 3 is adetail cross-section. Fig. I is a section on the line I 4; of

Fig. 3. Fig. 5 is a partial longitudinal vertical section, and Fig. 6 isa longitudinal vertical section showing more especially the printingmechanism of the machine. Fig. 7 is a partial horizontal section showingmore especially the laterally-movable paper-carriage.

In said drawings, l5 represents the keys; I6, the surrounding frame; 17,the shaft on which the numeral-wheels 18 are supported; 19, the pinionactuating one of the numeralwheels; 20, the segmental lever meshing withsaid pinion and also lioined to the type-segment 21 by a link 22 in suchmanner as to position such segment when it (the lever) is depressed. Thecarrying-leverof the numeral-wheel next adjacent to the wheel shownappears at 23. The keys are each provided with an offset or bend 25 onits stem adapted to engage the lever 20, and the offsets are graduatedin position, so that each key will be able to impart the proper amountof movement to the lever. The keys are made the medium of depressing thelevers 20, and to this end each key-stem has a shoulder 26, adapted tobe engaged by a springcatch 27, carried by a frame 23, when the key isdepressed or set by the linger of the operator. The frame 28 is unitedto an operatingframe 29 by links 30, and a bodily downward movement isimparted to frame 29 by cranks 3l on shafts 32, one of said shaftshaving a crank 33, the upper end of which carries a pin 34:, working ina slot 35 in the main cam 36, operated by the printing and addinghand-lever 37. The downward movement of frames 28 and 29 caused when thehand-lever is operated carries any key which may have been set downwardwith the frames, and such key imparts a movement to its segment-leverproportioned to the power of the key, and the segment-lever in turnactuates its corresponding numeral-wheel to a proportionate extent andpositions the typesegment to which it is attached with the figurecorresponding to the key at the printing'- center. It will be understoodthat there is a series of nine keys for each denomination embraced inthe machine and that such keys are duphcates of the ones shown; alsothat there is a separate numeral-wheel and segment-lever for eachdenomination, together with carrying devices for all the wheels exceptthe lowest. The keys are released from the catches by a horizontalmovement of frame 28, imparted to it at the conclusion of the printingoperation by means not shown, but which may be seen in my Patent No.568,021, of September 22, 1896.

The paper (seen at 38) is impressed upon the type by spring-actuatedhammers 39, of which there is one for each denomination and which arenormally held out of action by detents 40, but are released from thedetents by the tailpieces 41, actuated in part by the segment-levers 20and in part by a swinging cross-bar 42 and thehammer-releasing frames43. The action of the parts 39 to 43 is fully set forth in my Patent No644,287, of February 27, 1900. The paper enters the machine between theguides 44 and 45, is fed by rolls 46 and 47, and is guided upward byguide 48.

The present machine also embodies mechanism for returning the paper toits starting position after the completion of a vertical column andsimultaneously shifting the paper laterally in column-spacing, and thisreturning and shifting mechanism may be patterned after the designsshown in either of my Patents No. 628,176 or No. 644,287. The mechanismnow shown for this purpose is substantially like that of Patent No.644,287 and consists of the pinion 50, which corresponds to the pinion Cof the patent and is actuated in the line-spacing' movements of thepaper-rolls, the train of gears 51, 52, 53, and 54, the segment 55,actuated by gear 54 andsupported on shaft 56, and the hand-lever 57,mounted on said shaft and having a stud 58 engaging the shoulder 59 onthe hub of segment 55. The segment also carries a projection 60, whichencounters stationary stops at both limits of its path, the upper stopbeing' shown at 61 and the lower one at 62.

The locking mechanism is preferably similar to that of my pendingapplication, Serial No. 36,951, filed November 19, 1900, in which theedge 63 of cam 36 is serrated and is engaged by the serrated end 64 of alever 65, pivoted at 66 and having a spring' 67 urging itinto engagementwith the cam. This spring is controlled by the means set forth in mysaid application and consisting of a series of feelers 68, arrangedunder the path of the paper and pressed upward against the same by powerfrom spring 67. The connections between the feelers and the springconsist of the lever 65, the connecting-wire 69, the lever 70, pivotedat 71 and acting upwardly on the bar 72, supporting the series offeelers. The bar 72 is supported and moves with the laterallymovablepaper carriage, the longitudinal members whereof are shown at 73 and 74(the full details of a desirable construction of which carriage arefully set forth in my said Patent No. 644,287) and which also supportthe paper rolls and guides, as will be understood. The feelers areprevented from moving upward by the paper; but as soon as the bottom ofthe paper passes them they move upward and allow the spring 67 to throwthe lever 65 into engagement with the cam, thereby arresting both theadding and the printing mechanisms of the machine.

In order to insure the locking of the cam 36 by lever 65 when anypredetermined number of lines have been printed, I employ the followingmechanism: At is a rotatable dial the face of which is divided byindicating-marks into spaces which ordinarily will equal in number thenumber of lines which the paper is capable of receiving. The dialillustrated has ninety-four spaces, but may have any desired number, andit is provided with a stop-pin 81, adapted to encounter a stationarypointer 82 and prevent it making a complete rotation. This dial ismounted on a sleeve 83, loosely encircling a shaft 84, but capable ofbeing locked thereto by tightening the nut 85, so as to force the sleeveagainsta collar 86, rigid on the shaft. The sleeve is also rigid andpreferably integral with a pinion 87, meshing with a pinion 88 on theshaft 89, which is the shaft carrying the gears 53 and 54 of thepaper-returning mechanism. Pinion 88 is loose upon shaft 89, but iscompelled to turn with the latter whenever the laterally-projecting pin90, carried by the pinion, engages the arm 91, radiating from collar 92on shaft 89. Shaft 89 is turned by gears 53 and 54, but communicates nomotion to gear 87 or shaft 84 until the pin 90 and arm 91 engage. Thesleeve 83 is normally locked to shaft 84, but is released whenever it isdesired to change the relation between pin 90 and arm 91, so that theirengagement may take place earlier or later. This adjustment is effectedby turning the dial until the desired mark thereon is brought in frontof the pointer, as seen at Fig. 5, where the dial is set at the secondmark, indicating' that the engagement shall take place immediately afterthe second forward feeding movement of the paper. Obviously the dialmight be set at 94 or any smaller number. l/Vhen the shaft 84 is thusactuated by the engagement of pin 90 and arm 91, it gives a swingingmovement to an arm 93, rigidly attached to its farther end, and this armis connected by a bar 94 to an upward projection 95 on lever 65. The bar94 is slotted at the end connected to projection 95, and the arm 93 isalso slotted at the end joined to the bar, as shown, and at this latterjunction a spring 96 is employed tending to force the bar in a directioncorresponding to that in which it is moved by arm 93. The actuation ofshaft 84 through these devices moves lever 65 into locking position withthe main cam, and thus arrests the printing and adding, both of whichIOO are brought about by the movement of said cam, and as such actuationtakes place whenever any predetermined number of lines has been printedit will be seen that I am able by setting the dial at the desired numberto bring about the absolute locking of the machine whenever that numberof amounts has been tabulated and added in any column. The spring 96renders the impact of the lever 65 with the main cam a yielding impact,thereby avoiding' danger to those parts, without, however, impairing thelocking-action. The dial is located at the side of the machine where thetotal-printing lever is usually located. This lever is shown at 97 inFig. 5, together with some of the parts actuated by it. The bar 94 isconnected to the arm 93 bythe pin 98, fast in the bar, and to arm 95 bypin 99, fastin the arm.

I have shown in the drawings a number of features which have no bearingupon the present invention, among' which may be mentioned theinterlocking lever 100, angular shaft 101, through which the feed-rollsare actuated by means not shown, the movable plate 102, having anopening 103 for the pin 104, the spring 105, the cushioning contact 106,the bent link 107, connecting lever 57 to the pivoted lever 108,carrying the pusher 109 for shifting the carriage in column-spacing. Theconstruction and operation of all these parts is fully set forth in mysaid -application Serial N o. 36,951.

It will be understood that the shaft 84 will be rocked back after eachactuation by the return of arm 93 and that shaft 89 is turned back withthe backward rotation of gear 53, so that the locking-action will bereleased at each operation of the paper-returning' mechanism.

The details of the laterally-movable carriage will be found set forthfully in my said Patent No. 694,955, reference being made moreesespecially to Fig. 2 of the patent. Referring to Fig. 7 of thisapplication, 107 is the link receiving power from the reversing-lever57. This link is connected to an elbow-lever 201, pivoted at 202 andcarrying at the end of its long arm a pusher 109, adapted to engag'e thenotches 200 in the bar 74 of the carriage, and thereby to shift thecarriage laterally a column-space at each actuation, said bar acting asa spacing device. To prevent overthrow, I may employ the elbow-shapedlatch 204, which is joined to the elbow-leverI 201 by a link 205 andenters notches 207, located between the notches 200. I may also employ aspring-pressed dolly-roll 208, entering the notches 207, to insureuniformity in the positioning of the carriage, the roll being carried onthe end of the pivoted bar 209, which is pressed downward at all timesby the spring 210. Further details of the carriage will be found in saidpatent.
